Abstract

A pixel matrix including a first substrate, a plurality of pixel structures, a first electrode set and a common electrode is provided. The pixel structures are disposed on the first substrate in an array arrangement. Each of the pixel structures includes a pixel electrode. The first electrode set includes a plurality of first electrodes arranged along a first direction on the first substrate. Each of the first electrodes having a plurality of first openings arranged corresponding to the pixel electrodes and surrounding the corresponding pixel electrodes. The common electrode is disposed between the first electrodes and the first substrate and between the pixel electrode and the first substrate. A touch display device having the pixel matrix and the driving method thereof are also provided.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the priority benefits of U.S. provisional application Ser. No. 61 / 822,894, filed on May 13, 2013. The entirety of the above-mentioned patent applications is hereby incorporated by reference herein and made a part of this specification.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The invention generally relates to a pixel matrix, display device and a driving method. More particularly, the invention relates to a pixel matrix, touch display device and a driving method thereof.[0004]2. Description of Related Art[0005]A display apparatus having a touch-sensing function is generally implemented by a touch system and a display system independent to each other. System integration and cost reduction are unchanged developing trends of electronics industry. With progress of fabrication techniques, a touch panels is now successfully integrated with a display panel, so that a user can direct an electronic devi...
